When to Use the D86 Beam Width Measurement Method

Although the clip level method and the second moment method are the most popular methods of beam width measurement, other beam width measurement techniques such as the D86 method can be used with beam profiling cameras. Rather than using the 1D or 2D profile of the beam to determine the width, the D86 method uses the diameter of a 86.5% power enclosure as the beam width. In this blog post we describe the D86 beam width measurement method and the applications for which it is most appropriate.
